16 grassfires in Moree in one week

Fire and Rescue crews at Moree say they're frustrated with a spate of grass fires in and around the town.

Station Commander, Scott Beers, says his crews have been called to at least 16 fires deliberately lit on vacant blocks and in paddocks.

He says his firefighters are working with officers from Barwon Local Area Command to investigate the cause.

"They're doing a great job, they're doing what they can but it only takes a minute to start a grass fire and perpetrators can be well away before we're near them, so it's frustrating," he said.

"Unless they're caught in the act it's very hard to get witnesses so it really is a difficult situation."

Scott Beers says the fires are putting nearby homes at risk.

He says early investigations indicate none of the fires have been accidental.

"I would suggest 100 per cent of these fires are deliberately lit [because] we haven't had any lightning, there's no reason for the grass to spontaneously combust," he said.

"They are all deliberately lit and even though we have permanent firefighters in Moree we also rely on our retained staff to come in and back us up, so it really is a drain on resources and the community."
